What Is Opal Used to Make?
Opals are mostly found in Australia but also in parts of Europe, North America, South America and Africa. This gemstone has been mined since the times of the Roman Empire and is used in jewelry as a gemstone component. Opal comes as cabochons, faceted gemstones and beads. Because this gemstone can become brittle if not kept moist, opal is mostly used for jewelry worn in damper areas of the body such as on a necklace pendant.
